Based
on information available to us as of July 14, 2008. The sum of
the number of shares beneficially owned by the selling stockholders named
in this table and named in the table in the prospectus supplements dated
August 23, 2007, September 11, 2007, October 30, 2007, March 17, 2008,
April 29, 2008 and May 19, 2008, exceeds 6,499,134 shares of common stock
(the total number of shares offered pursuant to
the
|
|
prospectus
supplements) because certain selling stockholders may have transferred
notes or otherwise reduced their position prior to selling pursuant to
this prospectus supplement, and as a result we received beneficial
ownership information from additional selling
stockholders. However, the maximum number of shares of common
stock that may be sold pursuant to the prospectus supplements will not
exceed 6,499,134 shares.

|
The
number of shares of common stock issuable upon the exchange or redemption
of the notes assumes exchange of the full amount of notes held by each
selling stockholder at the initial exchange rate of 36.1063 shares of our
common stock per $1,000 principal amount of notes and a cash payment in
lieu of any fractional shares. The exchange rate is subject to
adjustment in certain events.
|

|
Based
on a total of 74,400,213 shares of our common stock outstanding as of July
14, 2008.
